Problems solved by technology

However, the yarn fiber density and uniformity of the existing products used for special protective clothing yarns are poor, the strength is low, and it is uncomfortable to wear; in addition, there are certain defects in warmth retention, washing resistance, flame retardancy and high temperature resistance. It will also produce a certain amount of toxic gas, so it cannot meet the environmental protection requirements. The raw materials used in the production process are polluting, which hinders the economic development of the same field.

Abstract

The invention relates to a method for producing aromatic polysulphone blended yarns, which mainly comprises: subjecting aromatic polysulphone and cotton fibers to processing steps in FA002A automatic plucker and the like; mixing aromatic polysulphone and cotton according to a ratio, and subjecting the performing primary, secondary and tertiary drawing steps in turn in HSD-961 drawing frame; subjecting the mixture to an automatic leveling in TD03-600 drawing frame to perform final drawing; and finally, spinning in a VORTEX861 vortex flow spinner. The aromatic polysulphone blended yarns have the combined advantages of aromatic polysulphone fibers and cotton fibers, retain the characteristics of heat resistance, flame resistance and high strength of aromatic polysulphone and wear more comfortable; the flame retardance of the aromatic polysulphone blended yarns is high, molten drop in flame is avoided, and little toxic gas is generated during carbonization; the electric-insulation performance and moistureproof performance are high; and the aromatic polysulphone blended yarns are nontoxic, safe and free from peculiar smell and pollution, and can create great economic benefit.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for producing aramid sulfone blended yarn. Background technique [0002] Aramid sulfone fiber is an aromatic polyamide high temperature resistant fiber, which has good properties such as heat resistance, thermal stability, high temperature dimensional stability, flame retardancy, electrical insulation, etc., and has a wide range of applications. However, the existing yarn products used for special protective clothing yarns have poor fiber density and uniformity, low strength and uncomfortable wearing; in addition, there are certain defects in warmth retention, washing resistance, flame retardancy and high temperature resistance, and carbonization It will also produce a certain amount of toxic gas, so it cannot meet the environmental protection requirements, and the raw materials used in the production process are polluting, thus hindering the development of the economy ...
